The present study assessed the structural and functional representation of the upper limb in a large cohort (N = 84) of typically developing children aged 6 to 10. The first task aimed at obtaining a structural measure of the representation of the arm, specifically the two segments that compose it: the forearm and the hand. Participants were asked…

Manual exploratory behaviors during object interaction that form the basis of tool use behavior, are mostly qualitatively characterized in terms of their frequency and duration of occurrence. To fully understand their functional and clinical significance, quantitative movement characterization is needed alongside their qualitative analysis.…

Fidget devices are often used in classrooms to help students move their bodies while attending to academic or behavioral directives. Devices range from small handheld tools such as spinners and tangle puzzles to larger full-body devices such as exercise balls. The current study provides a meta-analysis of the effects of fidget devices as academic…

Past research has shown that children's mental rotation skills are malleable and can be improved through action experience--physically rotating objects--or gesture experience--showing how objects could rotate (e.g., Frick, Ferrara, & Newcombe, 2013; Goldin-Meadow et al., 2012; Levine, Goldin-Meadow, Carlson, & Hemani-Lopez, 2018). These…

Various developmental studies have demonstrated that implied object weight is a key variable in children's interpretations of motion, such as predicting the objects' speeds. An additional bias in predictions of object motion is representational momentum (RM), where objects are anticipated to be found in a location farther along in the direction of…

Purpose: Studies have suggested that the use of visual information may underlie the benefit associated with an external focus of attention. Recent studies exploring this connection have primarily relied on motor tasks that involve manipulation of an object (object projection). The present study examined whether vision influences the effect of…
